Auto Electrical Services in Auckland – Professional Diagnosis & Repair
Electrical faults don’t wait for a convenient time to show up. One moment everything’s working fine, and the next you’ve got warning lights on your dash or a starter that won’t turn over. That’s where we step in. Our auto electricians provide accurate diagnostics and dependable repairs whether it’s a failed module or intermittent power loss.
Advanced Auto Electrical Diagnostics
We work with dealer grade tools to create full diagnostic report of your car. On the live diagnostic data and fault code analysis, we are able to isolate problems in control units, sensors, wiring, and other circuits. Whether your check engine light is on or your vehicle just isn’t behaving normally, we’ll find the real cause quickly and reliably.
- Complete ECU and module diagnostics
- Wiring integrity testing (resistance, continuity, voltage drop, corrosion)
- Electrical fault tracing
Starter Motor & Alternator Repairs
Your vehicle's charging and starting systems are vital. If your lights dim under load or your engine cranks slowly (or not at all), we’ll check and repair your alternator or starter motor to restore performance. Our repairs include component testing and replacements using OEM-grade parts.
- Starter motor diagnostics and rebuilds
- Alternator fault testing and bearing replacement
- Charging system evaluation and voltage regulation
Battery Testing, Installation and Maintenance
We test, supply, and install batteries for all car types. We check not just voltage, but cold cranking amps, alternator output, and drain currents ensuring your battery isn’t just charged, but healthy and safe.
- Battery voltage and charge-rate testing
- High-performance replacements from leading brands
- Maintenance of terminals, cables, and corrosion points
Window Regulators & Central Locking
If your windows won’t open or your central locking’s hit-or-miss, we handle diagnostics and repairs for actuators, switches, motors, and wiring. We repair or replace window regulators for both electric and manual systems. Every mechanism is tested for full function before handover.
- Window lift motor repairs
- Central locking solenoid and relay replacements
- Rewiring and switch testing
Sensor Faults & Check Engine Light Diagnosis
Sensor errors can reduce performance or cause limp mode. Using modern scan tools, we identify the sensor at fault O2, MAP, throttle, or wheel speed and verify it with real-world measurements. We will turn off your dash light only after resolving the underlying issue.
We Service All Makes and Models
Our electricians are trained on a variety of platforms, including Japanese hybrids and European brands. With years of practical experience, we offer quick, straightforward service for both common problems and complicated faults.
